Not a People Orientated organisation

I placed an order on takelot.com on Dec 27th and paid on the same day. Delivery date on my order reflected 3rd Jan and this was perfect as it was the same day I was due to leave for my camping holiday - My order included a 2 man tent for my kid and 2 camping blow up beds.....

Early on the 2nd I sent through an online enquiry to confirm that the 3rd is still my delivery date (tracking details on the order remained unchanged since the 27th) I advised that I cannot take delivery on any other date as I will be away on holiday and need the items ordered before then.

Now just before 5pm on 2 Jan my delivery date changes to the 4th on the order tracking and I receive an email that my order cannot be changed. I held up my end of the agreement - why can Takealot Change the date and I can't get out of the order.

This makes no sense - I have to go to Makro tomorrow to get my tent and blow up beds because I need it by tomorrow eve. Takelot then tells me that I must advise them once I get the sms and they will tell the courier not to deliver - Hello do I know also have to do their work for them. Can they please apply logic to this matter - deliver on the 3rd and I will accept the order - as was initially advised. Don't deliver on the 3rd and cancel the order - I will make alternate plans. I cannot even pick the phone and speak to someone. Emails take 8 hrs to get responded to
